CD3 and CD19 expression was low (1.7 ± 0.71% and 1.7 ± 0.43%, respectively), whereas CD14 and CD16 showed notably high expression (25 ± 4.9% and 24.8 ± 4.5%, respectively), suggesting that monocytes and NK cells are significant contributors to EV production in MM, while T and B cell contribution on such regard is comparatively minor. Here, CD14 is linked to Miyoshi myopathy.
